Inclusion Criteria:

In order to be eligible to participate in this study, subjects must meet all of the following criteria:

1. Ulcers of venous origin, as determined by clinical signs and symptoms (e.g. hyperpigmentation of the surrounding skin, history of swelling, varicosities, lipodermatosclerosis and/or dermatitis) or other assessments (e.g. venous reflux test). If the subject has multiple on the same leg and/or bilateral ulcers, the largest should be selected.

2. Venous insufficiency ulcers, of at least 1-month duration, which have not adequately responded to conventional ulcer therapy

3. Venous insufficiency ulcers between 2 cm2 and 16 cm2

4. Venous ulcer has not reduced in area ≥40% from baseline measurements during the 2-week screening period

5. Partial- or full-thickness VLU, including ulcers with tissue damage that extends through the epidermis and into the upper epidermis (papillary dermis), or into the deep dermis

6. Subjects are between 50 and 85 years of age.

7. Subject is expected to be available for 12-week follow-up

8. Subject, or their Legally Authorized Representative (LAR), has read, understood, and signed the IRB/IEC approved Informed Consent Form before screening procedures are undertaken.

Subjects who meet any of the following criteria will be excluded from participating in this study:

1. Ankle Brachial Index (ABI) of <0.7 or Toe Brachial Index (TBI) <0.5

2. Vasculitis, severe rheumatoid arthritis, and other collagen vascular diseases

3. Clinically significant medical conditions which would impair wound healing, as determined by the investigator, including renal, hepatic, hematologic, neurologic or immune disease

4. Signs and symptoms of infection, cellulitis, osteomyelitis

5. Necrotic ulcer beds

6. Subjects receiving hemodialysis or have uncontrolled diabetes: defined as A1C of greater than or equal to 12. An existing A1C value is allowed if completed within 3 months of subject screening.

7. Subjects who are currently receiving or have received at any time within one month prior to entry into the study, corticosteroids (>15 mg/day), immunosuppressive agents, radiation therapy, or chemotherapy. Anticipated use of the above agents will exclude subjects from entry into the study.

8. Wound unable to be debrided or subject not able to tolerate debridement

9. Subject not willing or able to comply with compression requirements

10. Subjects enrolled in other wound investigational studies within the past three months, or device studies within the past 30 days.
